Contact Mitsubishi customer relations and ask for a "one time consideration" for the service needed to correct this problem.

the part that commonly needs replacing is the chassis (part no. 955B298003). They might ask for that information.
thanks.

The timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.

Replace the two 3300uf caps on the PWB? how about the thermal sensor?

They have been made different colors so i cant say for sure, but thereare only two 3300 uf @16V caps on the PWB and you can get the thermalreistance if you need it at the following link but you would have toleave an email as they dont list alot of their little components. Justleave your model number and the name of the part your needing.

The fact that its making a chirping means the power supply is most likly ok. It probably the horizontal output transistor is shorted. Now the flyback transformer could be the cause of this  or the small coil between the horizontal outut transistor Base and the horizontal driver transformer could need to be taken out and the leads scrapped of paint and resoldered or the the HI voltage caps in the horizontal section could be shorted or leaky. Most of the time when these are bad the caps are split or show burning.  They are the 1.5kv disc caps Good Luck

Normally with DLP sets, the blinking lights will indicate a bad lamp or fan. If you have the owner's manual, the chapter on changing the lamp should be preceeded by a listing of the lamp indicators. Check also the lamp door and be sure that it is seated properly. There are a number of "safety" switches throughout the set that will cause this symptom if any of hte access doors are not closed properly.

If not the access doors or lamp, the ballast could be bad. It is important to look up the flashing code. Are there any other lights on the front? Temp? Power?

Thanks,
Dan

    Did you check the small fuses and resistors near to the convergence ICs? if they keep blowing there is a powering problem on the convergence board.

    read this website, they are saying that it is a common fault on this model, that the part that commonly needs replacing is the chassis (part no. 955B298003).

    They also say that Mitsubishi can cover out-of-warranty repair, try to give them a call, you find the number on the owner manual.

    Well, the voltages are ok, this do not tell me anything.
    More than voltages you should check if there is any error message.

    Regarding: main power no work

    not coming power pulse from micon.

    If you can provide more details on this, it can reveal something.

    If there is no power from power supply, tv won't startup, but you told me the led goes on.

    See if the led blinks a certain number of times, if light flashes at intervals of three times, for example, you will need to replace the bulb. Test the bulb ion any case.

    More than testing voltages out , see if you can spot any bad capacitor or resistor. Check the STKs on convergence board. Test high voltage board powering the lamp.

    I have the service manual and schematics for Chassis V29-V30-V31
    I put an upload here, you can download clicking here here.
    Many boards and diagrams are the same as in your V28 chassis.

    Rear projection TV have convergence STK ICs the same, only it works different, check the service manual.

Blinking "Timer" light for WD-62725


If this is a DLP, you may have problems on the FMT/DM boards in the sealed electrical chassis.

That's a big problem, because Mits doesn't make the DM/FMT boards available anymore. They are only available for rebuild from Mitsubishi and other qualified places.

There is a chance that there are some vented capacitors on the DM and FMT boards you might be able to replace, but it's for someone really comfortable with completely disassembling a set, soldering in 8 new caps and rebuilding the chassis.

Rebuilds will run you $400-$500 in rebuild costs and an additional $200-$400 in labor, depending on the joint.

Mitsubishi 62825 flashing green light on timer set wont come on,try reset same problem ?


Your main boards are bad. The FMT, DM, & Power Supply. They are no longer available, You have to have the chasis rebuilt. Mitsubishi is rebuilding these chasis. You have to pull it without any cut wires & ship to Georgia.

#1. replaced capacitors on power board. DM board FMT board .
# 2 on power board you need to chek caps. 3300mf x 35 v.QTY 2.
# 3 12 capacitor 1000mf x 16 v.
If caps 1000mf x 16 v . looked good. replaced anyway......

That set is plaqued with bad capacitors on the PWB, FMT and DM doards. Usually all problems assosciated with that model can be attributed to those capacitors. You can purchase a service manual that they will email you at the following link, and they will provide free tech support to help you straighten it out. Heres the link.

Green blinking light


the PWB , FMT and DM boards all have capacitor issuses with that chassis. If the power light is blinking there are 4 1000uf capacitors on the DM that need replacing. If you need more info let me know.

Wd62825 blinking green light


if you have replaced the caps on the DM and the FMT and power supply. you can unplug the e2p. the set will run without it if it is the problem, however it will take 5 to 10 minutes to boot up so be patient.
if it boots try turning it on. the picture should look terrible because no
light engine data is getting to the dm. chances are it is not the e2p, in the over 300 of these chassis i have repaired maybe 10 had a bad e2p. most likely the chassis needs to be rebuilt. check out www.tv-techs.com

Wd 62525 honeycomb pictues


The DM board wont cause that symptom. The DM only directs power that is recieved from the PWB to the ballast fans and etc. That sounds like a problem with the FMT. capacitors 1000uf @16volts numbers C8F21, C8F22, C8F19, and C8F27. those will cause distortions in the video on the V26 chassis. Let me know if you need more info

Mitsubishi wd-62825 dlp


The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill
